Surrounding the sun is a vast atmosphere of solar particles, through which magnetic fields swarm, solar flares erupt, and gigantic columns of material rise, fall and jostle each other around. Now, using NASA's Solar Terrestrial Relations Observatory, scientists have found that this atmosphere, called the corona, is even larger than thought, extending out some 5 million miles above the sun's surface -- the equivalent of 12 solar radii.

Natural resources worth more than US$40 Trillion must be accounted forGovernments and companies must do more to account for their impact and dependence on the natural environment - according to researchers at the University of East Anglia.

New research published today in the journal Nature Climate Change reveals that although some companies like Puma and Gucci are leading the way, more needs to be done to foster a sustainable green economy.

3,500 million years ago the Martian crater Gale, through which the NASA rover Curiosity is currently traversing, was covered with glaciers, mainly over its central mound. Very cold liquid water also flowed through its rivers and lakes on the lower-lying areas, forming landscapes similar to those which can be found in Iceland or Alaska. This is reflected in an analysis of the images taken by the spacecraft orbiting the red planet.

The gradually increasing complexity of user requirements and runtime environments of software demands software to be of more capabilities and thus become more complex than ever. In the past several decades, there was a trend that the scale of software has been increasing continuously. Nowadays, there are tens or even hundreds of million lines of code in a large scale software system.

The solar array that will provide power to NOAA's GOES-R satellite has been tested, approved and shipped to a facility where it will be incorporated on the spacecraft. The five sections of the solar array come together as one to resemble a giant black wing.

On May 13, 2014, the GOES-R satellite solar array panels were successful deployed in a Lockheed Martin clean room in Sunnyvale, California. The completed solar array was then delivered to Lockheed Martin's facility near Denver.

DENVER (June 24, 2014) - A University of Colorado Denver study examining collisions between bicycles and motorists, shows bicyclist safety significantly increases when there are more bikes on the road, a finding that could be attributed to a "safety in numbers effect."

The study focused on Boulder, Colorado, which has one of the highest rates of bicycling in the country at about 12 percent of the population.

The Greenland Ice Sheet is a 1.7 million-square-kilometer, 2-mile thick layer of ice that covers Greenland. Its fate is inextricably linked to our global climate system.

In the last 40 years, ice loss from the Greenland Ice Sheet increased four-fold contributing to one-quarter of global sea level rise. Some of the increased melting at the surface of the ice sheet is due to a warmer atmosphere, but the ocean's role in driving ice loss largely remains a mystery.
